The document discusses top tests that tablet PC manufacturers should carry out during product inspection, including touch screen testing using a testing machine, battery testing by charging/discharging the battery 20 cycles, screen adhesion testing using 3M tape, vibration testing using a vibration table, and environmental testing using an environmental chamber. Conducting these five tests can help manufacturers ensure quality and leave the competition behind.

26. To test battery charge/discharge:
1. Remove the battery protection board
27. To test battery charge/discharge:
2. Charge and discharge the battery 20 cycles
1. Remove the battery protection board
28. To test battery charge/discharge:
2. Charge and discharge the battery 20 cycles
1. Remove the battery protection board
3. Compare the actual capacity found to the rated capacity
29. If battery capacity tested is less than the rated
capacity, the tablet fails this test.
30. If battery capacity tested is less than the rated
capacity, the tablet fails this test.
35. To test screen adhesion:
1. Apply 3M tape to the tablet screen
36. To test screen adhesion:
2. Tear the 3M tape off the screen
1. Apply 3M tape to the tablet screen
37. To test screen adhesion:
2. Tear the 3M tape off the screen
1. Apply 3M tape to the tablet screen
3. Check that the screen is still firmly in place
44. To conduct vibration testing for tablet PCs:
1. Use units that have already passed AQL defect inspection
45. To conduct vibration testing for tablet PCs:
2. Place units in their retail packaging on the vibration table
at 200RPM for 2 hours
1. Use units that have already passed AQL defect inspection
46. To conduct vibration testing for tablet PCs:
2. Place units in their retail packaging on the vibration table
at 200RPM for 2 hours
1. Use units that have already passed AQL defect inspection
3. Check the units for functionality and performance
47. If the units tested maintain full functionality and
performance, the tablets have passed vibration testing.

56. To carry out environmental testing for tablet PCs:
57. To carry out environmental testing for tablet PCs:
1. Keep the units in an environmental chamber with a temp
of 55 C +/- 2 C and a humidity of 85% for 8 hours
58. To carry out environmental testing for tablet PCs:
1. Keep the units in an environmental chamber with a temp
of 55 C +/- 2 C and a humidity of 85% for 8 hours
2. Check the tablets’ functions and performance
59. If the units tested maintain full functionality and
performance, the tablets have passed environmental
testing.
60. If the units tested maintain full functionality and
performance, the tablets have passed environmental
testing.
